Minimize the function f() on the interval (a, b) with precision at least tol using the golden ratio (a special variant of ternary search) method. You should assume that variables f, a, b are already defined. You need to output the point of the minimum of the function using the standard print statement. Make sure you perform only one function call at each iteration! Sample Input 1: from math import sin a = 2. b = 7. tol = 0.000001 f = sin Sample Output 1: 4.712388985743289 Sample Input 2: f = lambda x: ***1.8 - 15*x + 4 a = 2 b = 30. tol = 0.000001 Sample Output 2: 14.158702029267767 Minimize the function f() on the interval (a, b) with precision at least tol using the golden ratio (a special variant of ternary search) method.
